APPARATUS FOR DISCHARGING BlLGE-WATER.

SPECIFICATION forming part of Letters Patent No. 241,313, dated May 10, 1881.

Application tiled October 25, 1880. (No model.)

To all whom it may concern:

Be it known that 1, JOSEPH J. DE KINDER, of Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented a new and Improved Bilgeater Pump for Ships and other Vessels, of which the following is a specification.

WVith the ordinary bilge-pumps it is impossible, when the vessel rolls heavily and quickly, to maintain a continuous discharge of thebilgewater, for as the vessel rolls to starboard the suction-pipe on the port side becomes bare and the water which is in it below the lower valve flows back into the bilge, while only the pump on the starboard wing draws water until the vessel rolls back to port, when for some time neither pump works until the water can collect on the port side, when the port pump will operate. Considerable time thus elapses on each roll of the vessel before a pump has filled its suction-pipe up to the lower valve, and by the time said pump begins to discharge the vessel will roll in the opposite direction. Thus the pumps work poorly and the water accumulates, and the result is that at every lurch the water rushes up in the wings of the vessel and injures the cargo; and on a steam-vessel the water surges up 0n-the stoke-hole plates and carries off ashes and coal into the bilge, thereby causing the pumps to choke.

The object of this invention is to overcome the above difficulties; and the invention consists in preventing the back flow of the bilgewater from the suction-pipes during the rolling of the vessel by alternately closing the valves of the suction-pipes by means of a self-acting pendulous weight, the operation of the parts being such that as the vessel rolls, so as to leave the bottom of either of the bilge-pump suction-pipes dry or out of water, the valve of such pipe will be closed and the back flow of the bilge-water in the pipe will be prevented, substantially as will be hereinafter set forth.

Figure l is a sectional front elevation of the device on line yy, Fig. 2. Fig. 2 is a sectional side elevation of the same on line ma, Fig. 1. Fig. 3 is a diagram showing the position of the weight or pendulum and valve rods on a roll to port.

Similar letters of reference indicate corresponding parts.

In the drawings, A represents a water-chamber provided on one side with a suitable pump, the piston barrel or cylinder of which is shown at B. Connected with the lower partof the water-chamber A are the suction-pipes G D, that are designed, respectively, tolead to the starboard and port bilges of the vessel. When the pump is in operation the bilge-water is drawn up through the suction-pipes (J D into the water-chamber A, and passes thence into the pump-cylinder B, whence the water is dischargediu the usual manner. Atthe openings of the pipes O D into the chamber A are formed the valve-seats c d, respectively.

From the top of the water-chamber A standardsE project upward and have a piu,f, passed horizontally through their tops, on which is fulcrumed the lever F, having two equal horizontal arms and an arm, g, depending centrall y and at right angles therefrom.

To the arm g is attached a heavy weight or pendulum, G, while to the extremities of the horizontal arms of said lever F are attached the valve-rods H H, that extend downward through suitable stuffing-boxes, h h, into the water-chamber A, and carry on theirlower ends the valves I 1, respectively, directly over the valve-seats c d. When the vessel is on an even keel the weight G hangs perpendicularly and centrally between the valve-rods H H. When the vessel lurches to port the weight G swings to port and operates through the lever F, which is'always held in' a horizontal plane by the weight G on the lever-rod and valve H I, causing the latter at once to close down on the valve-seat c, and thereby hold in the suctionpipe 0 by atmospheric pressure the water that may be therein, while at the same time the relative] y downward movement of the rod H lifts the valve 1 higher, thereby drawing water up through the port-pipeD into the delivery-chamber A, whence it is drawn through the pumpcylinderB. The position of the leverF, weight G, and rods and valves H H I I when the vessel lurches to port is indicated in Fig. 3. As the vessel lurches back to starboard the same action takes place, the movements of the parts being reversed. Itwill be seen that the up and down movements of the valve-rods HH are only relati ve to the suction-pipes O D as the water-chamher A and its rigid connections move with the roll of the vessel, while the lever F pr'eserves a horizontalline. Henceitisevidentthattheport suction-pipe D will retain the water in it when the "essel lurches to starboard, and the starboard suction-pipe G will also hold water by atmospheric pressure when the vessel rolls to port, and thatconsequentl y the operation of the pump designed to be connected with the pumpcylinder B will be continuous, however much the vessel may roll. \Vhen the vessel is on an even keel both valves I I are open, and consequently the suctioirpnmp connected with the pipe B will, when in motion, continuously draw water up through the suction-pipes H H.

The operation of the device when the ship rolls can be checked at any time by the insertion of a pin through the holes at made in the standard E and weight F, whereby the latter is held immovable.

By means of the nuts n a the valves I I can be adjusted so as to be given more or less travel.

Having thus described myinvention, I claim as new and desire to secure by Letters latent 1. A ships bilge-pump consisting of the following elements, namely: a pump for raising 25 water connected with a water-chamber, two bilge suction-pipes opening into said chamber with valves seated on said pipes, and a pendulous weight suitably connected with the stems ot' said "alves, operated substantially as herein set forth, whereby the rolling motion of the vessel will move the weight, alternately close the valves, prevent back flow of bilge-water, and insure a continuous delivery of water by the pump, as specified.

2. In a ships bilge-pump, the combination, with the standards E L, the chamber A, and the suction-pipes O D, provided with valveseats 0 d, of the valve-rods H H',provided with the valves I I, the lever F, provided with the downwardIyprojecting arm g, and the weight Gr, secured on the said arm, substantially as and for the purpose set forth.
